  • Patent number: 8950175
    Abstract: An exhaust-gas aftertreatment device for an internal combustion engine includes a catalytic converter having a tubular member which defines a volume housing a catalytic converter substrate. The volume housing the catalytic converter substrate communicates with an inlet portion for receiving exhaust gas from the engine and with an outlet portion for discharging the exhaust gas after catalytic conversion thereof in the volume. The device further has a pipe member within the tubular member which connects the inlet portion with the volume in the tubular member and guides the exhaust gas from the inlet portion in a first direction of flow. The pipe member opens downstream into a deflector which deflects the exhaust gas into the volume of the tubular member in a second direction of flow other than the first direction of flow. Unburned liquid fuel contained in the exhaust gas is deposited on the deflector for later evaporation.
